I will never ever share your contact information. It bothers me when companies share Email addresses and phone number with others — so I would never do that to my customers. If you are OK with getting an Email with a discount code, you might hear from me again, otherwise, this information will only be used for completing your order. Only PayPal will know your credit card number. I will not record any information about your bank account number should you choose to mail a check. It is safe doing business here.
